CLOCK-MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 467,354, dated January19, 1892.

Application filed August 3,1891- Serial No. 401,582. (No model.)

To all whom, it may concern: In illustrating my invention 1 have shownBe it known that I, FREDERIO A. LANE, of a clock -movement which whenrunning at New Haven, in the county of New Haven and the desired rate isfound to rotate the arbor State of Connecticut, have invented a new A ofthe first wheel of its escapement-train 5 5 Improvement inClock-Movements; and I do once in three hours. In order to convert thathereby declare the following, when taken in running rate of the traininto time, I rigidly connection with accompanying drawings and attach tothe projecting outer end of the said the letters of reference markedthereon, to be arbor a wheel B, having thirty teeth and cara full,clear, and exact description of the rying an intermediate wheel C ofeight teeth. 10 same, and which said drawings constitute part This Wheelmeshes into a cannon pinion D,

It will be understood that of thepointers is not derived from a shaft of the minute-pointer, which is notshown, will 20 the escapement-train rotating once an hour be fastened tothe outer end of the cannonand called the center shaft, but from onepinion, while the hour-hand, which is also not or more Wheels driven bythe said train and shown, will be fastened to the outer end of adaptedin size and in the number of their the socketwvheel.

Having fully described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. In a clock, the combination, with an escapement-train, of a wheelfixed to an arbor of the said train and carrying an intermediate wheel,a cannon-pinion meshing into said arbor-wheel, and a socket-wheelmeshing into the said intermediate wheel, the said Wheels and pinionbeing adapted in the number of their teeth to convert the running rateof the said arbor into time, substantially as clescribed.

2. In a clock, the combination, with an escapement-train having one ofits arbors rotating once in three hours, of a Wheel having thirty teethfixed to the projecting outer end of the said arbor and carrying anintermediate wheel having eight teeth, a cannon-pinion having ten teethmeshing into the said arborwheel, and a socket-Wheel having thirty-twoteeth meshing into the said intermediate wheel, substantially as setforth, and whereby the said Wheels and pinion convert the running rateof the escapement-train into time. In testimony whereof I have signedthis specification in the presence of two subscribing witnesses.
